neo22s / emailvalidator Goto Github PK

what is checkdnsrr ?

Good day,
When I tested your code, it only checks for valid MX-Records without really checking whether it's really exist or not.
You can input random non exist email address, like "[email protected]" and the json will still returns true.
So in summary, this isn't a true email validator.

Hello, I found your project linked from an entry in Sendy Forum. I'm looking for a script like your by my only worry is if using it will be accepted or rejected by great players like hotmail/yahoo/gmail when it comes to validate lots (hundreds/thousands) of emails.

Do you know any reference or by own experience if the IP address hosting this script may be blocked by ESP's or even added to any RBL?

Thanks in advance!
